BIO | Cut drills are specially designed to be used for a standard sequential osteotomy surgery and also one drill guided surgery. The drills are extremely sharp and will keep a sharp edge for multiple uses. To reduce the likelihood of surface staining, the drills should be cleaned immediately after use and all blood and debris should be removed with a regular nylon tooth brush. The drills should not be left overnight in an autoclave in a moist environment. If surface staining should occur, the functionality of the drills is not affected and the stain can be removed with a tooth brush and non-gel tooth paste.
